Where do we find flow batteries mostly nowadays? They add value when we store large amounts of electricity for long periods in external tanks.
Increasing The Amount Of Stored Energy May Be Simple
Increasing the amount of stored energy may be as simple as increasing the amount of electrolyte.
Renewable Energy Storage Is An Important Application
So where do we find flow batteries mostly nowadays? Well, renewable energy storage is an important flow battery application. You see, solar panels only produce electricity during daylight, while wind generation depends on prevailing weather.
A flow battery can store surplus electricity when production is high. It can then return that electricity to the grid when demand increases again, or darkness falls.
Flow Batteries May Also Support Electricity Grids
Flow batteries may also support large electricity grids. Power demand fluctuates throughout the day. Electricity networks must constantly balance supply and demand.
Large battery systems can absorb excess electricity and release it later. This can reduce pressure on conventional generating plants.
Smaller Electricity Micro Grids Are Another Candidate
Smaller micro grids are already serving locations such as factories, campuses, communities, and remote facilities. A flow battery can provide longer-duration energy storage, and work alongside solar panels, wind turbines, and conventional generators.
Commercial and industrial sites may also use flow batteries to manage their electricity consumption. They may do so during periods of high demand, reducing reliance on more expensive peak-time electricity.
What If Low Weight And Compact Size Are Essential?
Flow batteries generally do not suit applications where low weight and compact size are essential. This opens the door to conventional batteries in mobile phones, laptops, and electric vehicles.
Flow battery strength lies in stationary energy storage, where space is available. Then they become a durable and flexible solution!
